Windows only: Free virtual archive tool Pismo File Mount can help you cut down on unnecessary CD burning and folder space by mounting compressed and ISO files as virtual drives. There are lots of utilities and means to do this, of course, but Pismo offers the simple route. Just right-click on a disc image or zipped file and choose "Mount" or "Quick Mount," and you can assign the folder to, say, drive Z:, or just have its contents pop up in a window. Grab what you need, close it down, and you're done. Pismo File Mount is a free download for Windows systems only.
